ADJUSTABLE DOOR-VISE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed May 1'7, 1910. Serial No. 561,818.

To all whom it may concern:

Be it known that we, WILLIAM T. KEN- NEDY and GEORGE C. Pnrrrr, citizensof the United States of America, residing at Lonerock, in the county ofKossuth and State of Iowa, have invented certain new and usefulImprovements in Adjustable Door-Vises, of which the following is aspecification, reference being had therein to the accompanying drawing.

Vhen hanging or fitting doors it has often been found necessary to planeor shave one or both edges thereof in order to have the same fit theframe or swing freely thereon after the same is hung. And it has alsobeen found very difiicult to hold the door in its desired position whilethe same is being trimmed or the hinges or look is being placed thereon.

Therefore the object of this invention is the production of a door clampor vise which will firmly hold a door in the desired position while oneedge thereof is being planed or worked upon.

Another object of this invention is the production of a portable doorclamp or vise which is simple in construction, eflicient in operationand which can be readily carried from place to place.

WVith these and other objects in View, this invention relates to certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawings: Figure 1 is a top plan view of the vise. Fig. 2 is anenlarged section taken on line 22 of Fig. 1. Fig. 3 is a front view ofthe clamp or vise.

Referring to the drawings by numerals, 1 designates the base whichcarries a pair of vertically extending frames 2. The frames 2 aresupported at their outer ends by means of feet 3 which are provided upontheir under surfaces with cushions 1. The frames 2 are spaced apart attheir inner ends and a strap 5 is carried by the upper end of each frame2 and overhangs the inner end thereof as clearly shown in Fig. 3. Aroller 6 is interposed between each strap 5 and the base 1 and comprisesan eccentric portion 7, which is covered with leather or any othersuitable material, and a drum portion 8. A bolt 9 passes through theroller 6 having its lower end embedded in the base 1, and its upper endpositioned in an aperture formed in the strap 5, near the outer endthereof. A

nut 10 is threaded upon the upper end of the bolt 9, thereby preventingthe same from being accidentally displaced from the strap 5.

A work supporting plate 11 is carried by the base 1 and has alongitudinally extending rod 12 secured to the under surface thereof.Said rod 12 is secured to the plate 11 by means of eyes 13 and said rod12 is provided with enlarged heads 14; to prevent the longitudinalmovement thereof relative to the eyes 13. The base 1 is provided with atransversely extending notch 15 in which the rod 12 is adapted to work.Eyes 16 e11- gage the rod 12 as shown in Fig. 2, and nuts 17 arethreaded upon the lower ends thereof for holding the same in engagementwith said base 1; the nuts 17 being countersunk so as to keep the sameout of engagement with the floor.

An abutment block 18 is carried by the rear end of the plate 11, and isadapted to be engaged by the work carried by the vise. Pins 19 arecarried by the front end of the plate 11, to which pins are attached therespective ends of the flexible member 20. The flexible member 20 passesaround the drum portion 8 of each roller 6 and in back of the abutmentblock 18, to which block it is fixedly secured.

It will be obvious that when the work, a door for example, as shown indotted lines in Fig. 2, is placed upon the plate 11, with one endagainst the abutment block 18, and the work pushed forward, therebypushing the plate to the position shown in dotted lines in Fig. 1, theflexible member will be drawn around the drum-portions 8 of the rollers6, thereby turning the eccentric portion to the position shown in dottedlines in Fig. 1, and firmly clamping the work between the eccentricrollers. It will therefore be obvious that the harder the work is pushedagainst the block 8, the tighter the work will be gripped. It will befurther obvious that by having the flexible member 20 secured to andpassing around the back of the abutment block 18, the block will begreatly reinforced thereby and the pull will be direct upon the flexiblemember.

\Vhat we claim as our invention is:

1. A clamp of the class described comprising a base, a bodily movablemember, abutment means carried thereby, eccentric rollers carried bysaid base, flexible means secured to said bodily movable member andpassing around a portion of said rollers for rotating the same when saidbodily movable member is actuated.

2. A clamp of the class described comprising a body, a plate slidablymounted thereon, an abutment block carried by one end thereof, rollerscarried by said body, said rollers provided with an eccentric up perportion and a reduced lower drum portion, a flexible member wound aroundsaid drum portions and secured to the back of said abutment block, pinscarried by the front of said plate and the end of said flexible membersecured thereto.

3. A clamp comprising a body, a plate, said body provided with atransversely extending notch, a rod secured to the under surface of saidplate, eyes carried by said body and engaging said rod for holding theplate against displacement from said body, work gripping rollers carriedby said body,

and means cooperating with said rollers and plate whereby when saidplate is shifted upoin said body, said rollers will be actuate 4. Aclamp comprising a base, a worksupporting plate carried thereby, anabutment block carried by said plate, eccentric rollers carried by saidbase, flexible means passing around the lower ends of said rollers andin back of said abutment block and having its front ends attached to thefront end of said plate for reinforcing said abutment member.

In testimony whereof we hereunto affix our signatures in presence of twowitnesses.
